Backend Engineer (Typescript)

We’re hiring a Backend Engineer to join our Integrations squad. You’ll be at the core of building and maintaining integrations between Cryptio’s SaaS platform and the crypto ecosystem’s richest set of third-party APIs, supported by a modern engineering stack (TypeScript, Nest.js, Temporal, Kubernetes, AWS, Docker).

What You’ll Do

• Write production-grade TypeScript, bringing new integrations online and maintaining existing ones
• Own the end-to-end process: scope, document, and test your code for reliability
• Collaborate with Product and other engineers to make sure integrations meet customer needs
• Map messy, evolving data models into unified schemas
• Monitor health, resolve data inconsistencies, and proactively fix or improve integrations
• Contribute to architecture decisions to enhance scalability and reliability

• Has 5+ years of software development experience and confident working with TypeScript
• Has hands-on experience integrating third-party APIs (REST, GraphQL) and wrangling with OAuth/JWT/auth flows
• Brings clear communication—comfortable switching between technical and non-technical audiences
• Thrives in fast-paced, collaborative teams
• Has an analytical mindset, enjoys problem-solving, and is excited by crypto and fintech
• Communicates fluently in English, written and spoken
